Technical field
The invention belongs to agricultural plant protection field of mechanical technique, be specifically related to a kind of air-assisted type spraying machine air inlet adjusting device.
Background technology
In recent years, fruit tree diseases and pests harm is serious, brings huge economic loss to orchard worker.Manually dispenser is the main insecticide-applying way using in China orchard at present, but its agricultural chemicals availability is low, and environmental pollution is serious, and takes time and effort.From last century end, China has just started the research to accuracy pesticide applying technology, although obtain certain achievement, but still the shortcoming such as ubiquity dispenser efficiency is low, target specific aim is poor.Accuracy pesticide applying technology not only can improve output, reduces the pollution of agricultural chemicals to environment, and can improve agricultural chemicals utilization ratio, improves pesticide application technology level.Therefore accuracy pesticide applying technology is to preserve the ecological environment, and realizes the road of the certainty of harmony between man and nature development.In recent years, although the accuracy pesticide applying technical research of China makes some progress, but current orchard air-assisted type spraying machine, the change that cannot realize air output by the size of control orchard air-assisted type spraying machine intake is to adapt to the accuracy pesticide applying of known top fruit sprayer volume size and fruit tree distance.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of air-assisted type spraying machine air inlet adjusting device, can adjust according to the tree crown size of fruit tree the size of air-assisted type spraying machine air inlet, change the size of air-assisted spraying fan delivery, thereby realize garden accurate dispenser, improve the availability of agricultural chemicals, reduce the pollution of environment.
To achieve these goals, the technical solution used in the present invention is:
A kind of air-assisted type spraying machine air inlet adjusting device, comprise the left water conservancy diversion bellows 7 and the right water conservancy diversion bellows 14 that are fixed on sprayer chassis 3, in bellows, all have and be communicated to the shower nozzle 16 of medicine-chest 17 and the wind direction centrifugal blower 8 towards shower nozzle 16, it is characterized in that, bellows air inlet is provided with taper air inlet device 12, on air inlet device 12, be fixed with the circular baffle plate 11 with multiple scallop holes coaxial with it and that can rotate along axle, baffle plate 11 is controlled and is rotated the change that realizes bellows air inlet air quantity by stepper motor 9.
The inner cross-sectional area of described air inlet device 12 equates with centrifugal fan 8 cross-sectional areas, and coaxial with centrifugal fan 8, outer end cross-sectional area is 2 times of inner cross-sectional area, and outer end is fixed with the fixed dam identical with baffle plate 11 structures, and outer end-stopping plate center is provided with minor axis 10.
The scallop hole area of opening on described baffle plate 11 makes the masked area of baffle plate 11 equate with the inner cross-sectional area of air inlet device 12.
The edge of described baffle plate 11 is to the rollover folding near bellows, and the outside of turnover part is provided with the annular rack 19 that the gear 13 that is connected with stepper motor 9 matches, and drives baffle plate 11 to rotate by gear 13 by annular rack 19.
Described adjusting device is installed on tractor 1, and the personal control rotating in order to control step motor 9 18 being connected with stepper motor 9 is installed on tractor 1 simultaneously.
The present invention compared with prior art, can be by regulating personal control control step motor to drive the motion of baffle plate, thereby regulate the area of water conservancy diversion bellows air inlets, realize the change of orchard air-assisted type spraying machine intake, thereby realize the accuracy pesticide applying for known top fruit sprayer volume size and tree crown distance, reduced the pollution of chemical pesticide to environment, improved drug delivery level, and control system is quick on the draw, control precisely.
